How to Clean a Front-Load Washing Machine
Front-loading washing machines are more efficient than top-loaders but infamous for developing a persistent musty smell caused by mould growing in the door gasket and drum. It's one of the most common cleaning complaints in Toronto homes. Here's how to clean it and prevent the problem from returning.
Why Front-Loaders Develop Smell
Front-loaders use less water than top-loaders, which means residue from detergent, fabric softener, and body soil isn't fully rinsed away. This residue accumulates in the drum and door gasket, providing a food source for mould in the warm, damp environment. Closing the door when not in use traps moisture, accelerating mould growth.
Cleaning the Door Gasket (Most Important Step)
The rubber door gasket is where mould grows most aggressively — it's dark, damp, and collects residue in its folds:
- Pull back the gasket folds and inspect the entire inner surface with a flashlight
- For black mould spots: mix a solution of 1:1 bleach and water (or use undiluted white vinegar for a bleach-free approach)
- Apply with a cloth or old toothbrush, working the solution into every fold and crevice
- Let sit 5–10 minutes for bleach, 30 minutes for vinegar
- Wipe thoroughly with a clean damp cloth, then dry with a dry cloth
- Remove any small items (coins, debris) that have accumulated in the gasket folds
Cleaning the Drum
Run a drum-clean or self-clean cycle if your machine has one. If not: add 2 cups of white vinegar to the detergent dispenser and run a hot wash cycle (empty drum). Follow with a second cycle using 1/2 cup of baking soda in the drum. The vinegar removes residue and kills bacteria; the baking soda neutralizes odour. Wipe the drum interior with a clean cloth after the cycles complete.
Cleaning the Detergent Dispenser
Remove the dispenser drawer (usually pulls straight out) and soak in warm soapy water for 15 minutes. Use a toothbrush to scrub all compartments — detergent and fabric softener residue builds up here and feeds mould. Rinse, dry, and replace.
Cleaning the Filter (Often Forgotten)
Most front-loaders have a filter at the bottom front, behind a small access panel. Place a towel underneath and have a bowl ready — opening this releases collected water. Unscrew the filter cap, let the water drain, then remove the filter and rinse it under running water. Use a toothbrush to clear debris from the filter housing. Replace and close the access panel. This should be done every 1–2 months — a clogged filter causes drainage problems and odour.
Preventing Future Smell
- Leave the door open between uses — this is the single most effective prevention step
- Remove laundry promptly — clothes sitting in the drum for hours add to moisture and odour
- Use only HE (high-efficiency) detergent — standard detergent over-suds in low-water machines
- Use less detergent than you think — the dosing instructions on most bottles are too high, leaving more residue
- Run a drum clean cycle monthly
- Wipe the gasket dry after each load
